Expert Vacuum Pump Remanufacturing

Best Warranty in the Business

2 Year Warranty: All ADVACO pump rebuilds are covered by our exclusive two year warranty, from the date of installation, against defects in parts and workmanship.

ADVACO offers complete remanufacturing services for most major manufacturers of high vacuum blowers (roots-type blowers) including Alcatel, Edwards, Leybold, Stokes, Roots, and Aerzen.

ADVACO’s in-house machine shop has perfected manufacturing techniques that allow us to address costly “out-of-specification” major parts – such as the drive and driven lobe assemblies – resulting in high quality and cost-effective rebuilds.

The Blueprint Process


  • Via state-of-the-art, EPA compliant systems


  • Certified Vacuum Technicians utilizing specially designed and calibrated instruments will thoroughly inspect all of the unit’s components (including electrical and diagnostic systems) vs original OEM specifications.
  • All consumable items quoted for replacement. Major components that do not meet original OEM specifications are quoted for replacement or re-manufacturing in our in-house machine shop (at considerable cost savings).


  • Unit will be re-assembled in one of our dedicated manufacturing cells.

Testing/Quality Control

  • Extensive post re-manufacturing testing via proprietary software/hardware generating graphical data certifying both ultimate vacuum and pumping speed.
  • Applicable equipment software verified and re-set (run hours, etc.).
  • Inboard and Outboard Helium Leak Testing
